Title: Superconductive element
Inventor: TAKEMURA YASUHIKO
IPC: H01L39/22
Filed: 1989-03-31
Abstract: PURPOSE:To enable an element of this design to operate at a temperature higher than that of liquid nitrogen by making the advantage of a fact that a voltage is induced through the movement of a magnetic flux by a Lorenz's force when a current flowing through a superconductor in a magnetic field is made larger than a threshold value. CONSTITUTION:An MgO single crystal film 4 is formed on an Si substrate 3, and a Y-Ba-Cu-O superconductor polycrystalline film 5 is formed thereon. The substrate 3 is processed through an IC technique to form a MOS-FET 6, and moreover a capacitor 9 is joined for the formation of a memory element. The element is cooled with liquid nitrogen as a magnetic field is applied to it, and when a current larger than a threshold current is inputted into it once, it keeps outputting an output voltage even after an input signal cases. The storing of information can be made possible basing on that the voltage concerned is outputted or not.

Abstract: PURPOSE:To eliminate the need for an electric power device etc. by providing air intakes and outlets in a decoration chamber transparent from outside, and rotating a display plate by air pressure from the air intakes to utilize wind pressure during automobile traveling for the drive source of the decoration plate. CONSTITUTION:When an automobile travels at a constant low speed, a display plate 9 is energized with each spring 10 to be in a full line position, consequently the displays A, B, and C on the display wall 5a in a middle chamber 5 can be seen from outside. On the other hand, when a traveling speed becomes a given one or more, an air flow rate, that is wind pressure, taken in air intakes 4a becomes high, and air flow passes the air introduction holes 8 of a boundary wall 7a from a lower chamber 4 to push the display plate 9 upward. Then the inflow air in the middle chamber 5 moreover passes the air introducing holes 8 of a boundary wall 7b to be led to an upper chamber 6 to be discharged outside from air outlets 6a. Consequently the display plate 9 stands along the display wall 5a as shown with a virtual line in the middle chamber 5, as a result, A, B, and C displayed on the display surface 9b are changed to D, E, and F, and the D, E, and F can be seen from outside.

IPC: G11B27/22
Filed: 1983-05-13
Abstract: PURPOSE:To set an optional time for an unrecorded part and to detect easily the unrecorded part the designated time length, by using a time setting switch to set the time. CONSTITUTION:An optional detection time for the unrecorded part is set by a time setting means 11 for unrecorded part and displayed to a display part 12. When a start means 13 for detection of unrecorded part is turned on, a means 14 which traverses a tape quickly after rewinding it drives a mechanism 15. Thus the tape is quick traversed after it is rewounded. During this quick traversing mode an unrecorded part detection means 16 detects the time of the unrecorded part. A comparing means 17 compares the set detection time for unrecorded part and the detected time for the unrecorded part. If the coincidence is obtained from this comparison, a signal is sent to a means 18 from the means 17. The means 18 rewinds the tape back to the head of the unrecorded part and sets the tape in a record waiting mode. Then the record waiting state is obtained.

Title: Fuel assembly for boiling water reactor
Inventor: KINOSHITA HIDEAKI
IPC: G21C3/322
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To make compatible improvement of capturing performance of foreign articles and a necessary coolant flowrate by forcibly inducing mixed foreign articles in the coolant flowing in from the lower end of a fuel assembly for a boiling water reactor and forming the coolant flow path at the location small and the other part large. SOLUTION: The lower tie-plate 3e of an assembly for a boiling water reactor is constituted so that coolant W flowing in the coolant inflow holes 3j is rotated by a rotation mechanism 4 and mixed foreign articles are sent away outside. This mixed foreign articles is prevented to flow in to the fuel element side as the flow path cross sectional area in the coolant flow path hole 3m outside is small. As the coolant flow path hole 3m inside where the mixed foreign articles does not flow in is large in the cross sectional area and so by sufficiently reducing the pressure loss against the coolant water on the whole, power as the fuel assembly for boiling water reactor can be ensured.

Title: Magnetic head for vertical recording
Inventor: HAYAKAWA ATSUNORI
IPC: G11B5/29
Filed: 1983-05-12
Abstract: PURPOSE:To decrease the counter areas of magnetic materials between channels when the record/reproduction is carried out among plural channels, by replacing the magnetic ferrite of a magnetic core which gives no effect to the record/ reproduction characteristics with a nonmagnetic matter. CONSTITUTION:Magnetic cores 4a' and 8a' have satisfactory shapes to form magnetic paths for the 1st and 2nd record/reproduction main magnetic poles 1 and 7. Then nonmagnetic cores 10 and 11 are set at the side where contacts are secured with cores 4a' and 8a' and at the side not opposed to a magnetic recording medium 2. Thus the magnetic ferrite of a magnetic core having no effect to the record/reproduction characteristics is replaced with a nonmagnetic matter. This decreases the counter areas of magnetic materials between channels when the record/reproduction is carried out among plural channels and also reduces the crosstalk of magnetic flux among channels.
